user254: There are two tags on the main site, lay-buddhism and laity tags.
Neither has a description (i.e. a wiki summary).
Do they mean the same thing? Should they be merged, with being one be made a synonym of the other?
They might be quite important/useful tags for some users.

user157: To me these are different concepts.
lay-buddhism. A Buddhist sect/movement without a significant monastic component e.g. Triratna Buddhist Community (where I practice)
laity - the lay community within any Buddhist school or sect
I have to say though the I'm not sure whether they are used like that but I see the concepts as different. If they are going to be useful then I think they should have a tag wiki each and probably I bit of retagging is required. I'd be happy to do that or defer to yourself as you see fit.
Hope that's useful
EDIT
Actually I notice that the lay-buddhism tag now has a description which is different from my definition which might invalidate my comments
