 ====== Welcome ======
-Welcome to the topas wiki website!  Everyone who is a registered member of the wiki can contribute to it and is very welcome to do so.
+Welcome to the topas wiki!
-\\
-\\
+This site has been set up for the community to share ideas and tips for Topas and powder diffraction analysis more broadly.
-In January 2024 we updated to site to php 8 and did some redesign.  You now edit pages using the grey icons on the right.  Let John know if there are any problems.  There may be some formatting problems that need ironing out post upgrade.
-\\
+Read access is open to everybody, but you need to set up an account to contribute.  **We've had to disable old accounts and turn off the auto-registration to prevent hacking.  Information on how to register is on the [[how_to_contribute|how to contribute page]]**.
-\\
-On the left you'll find links to pages that we think you'll find most useful.  More general links are in the top bar.
+Writing wiki pages is easy and there's a quick guide at [[how_to_contribute|how to contribute (registered users only)]].  Please do contribute!
-\\

+In different areas of the wiki (see the links on the left you can):
-If you're looking for John's topas webages, they've recently moved to [[https://topas.webspace.durham.ac.uk/|topaswebspace.durham.ac.uk]].
+  * Browse through a list of topics contributed by people
-\\
+  * Browse macros contributed by people
-\\
+  * See online versions of the manual
-Registered users can contribute to most of the pages (e.g. topics, user macros, forum, tutorials).  Some pages (e.g. the manual and alphabetical keywords) contain reference material that's read only.  The topics page is an alphabetical list of links to important topics in topas.  User macros is where you can contribute macros you've developed or find ones others have made.  The forum is where you should ask and answer questions.  You can set your forum account up so you're emailed automatically when new topics and answers are posted.  Alphabetical keywords and manual pages are reference material taken from the topas documentation.
+  * Find data files associated with John, Robert and Andreas' [[book|Rietveld textbook]]
-\\
+  * Find various information repositories contributed by the community
-\\
+  * Find links to other Topas-related resources
-We hope that these pages will develop into a useful reference site for users of all flavours of topas as well as other Rietveld software.  As with any wiki, the information on open-edit pages is only as reliable as the community who contribute.  Please help us to keep things in good shape!
-\\
+A few of the wiki pages are read-only, but please contribute to the others.  As with any wiki, the information is only as reliable as the community who maintain it, so please do correct any errors you find.
-\\
-Finally you'll notice a link to the TOPAS Rietveld book.  This contains links to files and datasets from a text by Robert Dinnebier, Andreas Leineweber and John Evans on Rietveld refinement using Topas.
+The site was updated following a shift to php 8 in January 2024, so please let John know if you find any problems.

 To reference the topas wiki origins or jedit you might like to use "Evans, J. S. O. Advanced input files and parametric quantitative analysis using Topas. //Materials Science Forum 651//, **1** (2010)" or one of the other articles in the [[http://www.scientific.net/MSF.651|special issue of materials forum]] which documents the Trento meeting where the wiki was first suggested.  There's description of the topas symbolic language etc in: Coelho, A. A., Evans, J. S. O., Evans, I. R., Kern, A. & Parsons, S. The TOPAS symbolic computation system. //Powder Diffraction// **26**, S22-S25, doi:10.1154/1.3661087 (2011).
