* I heard that there might be a rule in edit guile line which would go like this:
If there is already a template heading on a wiki age, then the "stub" template should go to the footer.
My suggestion to guidelines would be that "stub" template should always be in one place. Either always on top, or always on bottom, to lower amount of confusion about it.
* Don't use "pseudo" namespaces. If You really need need new namespace: configure it.
* Laguage: install finally separate wiki instance for each language. That way we could finally use proper tools for translating articles and for linking to different language versions (It is possible to even install new wiki instace on the same database. During instalation You just define new prefix, like "de_" and all database object will be made with such prefix. And You can configure it to use the same userbase as english version. And You can point to English version as a source of images and files for the all instances)
* If, for some bizarre reason, we won't be having couple of instances for languages then in guildelines there should be rule that every page in language different than English should be in proper namespace. That includes categories and templates
* In cases like this it would be better to use subpages. Subpages are better because:
a) You can not confuse them with namespaces
b) They automatically give link to "parent article". For example here You can see link to "Template:Documentation subpage" under title of article. Although it does not work in our wiki. Either because we have to old version, or we have this disabled (it is possible to disable this for each namespace separately or for whole wiki)
c) it is possible to make links relative to the article. Link like this: [[../Downloads]] in PyRPR/Introduction, would linkt to [[PyPRP/Downloads]], and in [[3dMax/Introduction]] would link to [[3dMax/Downloads]]. It won't work in "namespace" convention. Such behavior us useful in making of templates
Having sad that: I think that we should reconsider to not use neither nemaspaces, nor subpages. I mean: what's wrong with titles like this: "Introduction to PyPRP", "Introduction to 3d Max", instead of titles like this: "PyPRP:Introduction", "3d Max:Introduction".
* credits of articles usually don't need to be in directly in article. For that a list of contributors in page history is enough.
* normal users can not delete pages so they must put template {{del}} instead (with proper explanation in the comment od edit). Admins should check this category, and either delete those pages, or remove {{del}} template (also with proper explanation to why).
* names of categories should be plural
* when categorizing try to put as much relevant categories as possible. So, for example, instead of putting [[Category:Tutorials]] and [[Category:Blender]], it's better to put just [[Category:Blender tutorials]]
