Use of Level 1 section headings
I just had a first stab at some editing an existing entry, and creating a new one. One small thing I noticed: all of the pages I've seen use Level 1 headings for the main sections, but this is discouraged by the MediaWiki documentation (esp. since Level 1 is already used for the main heading of each entry). See e.g. here:
So maybe it would be better to change those to level 2 (also in all cases I've seen the child sections use level 3 headings)? Not a big deal of course but it's a bit ugly and it's probably easier to fix this now than postponing it to a later stage (also existing entries will most likely be used as a template for creating new ones, so the problem will get progressively worse if left as it is). I suppose this is also something that might mess up attempts at automated text extraction.
