I was searching the web to see real good q3map2 manuals. I’ve found some excellent guides, but there were a bit outdated. I thought I could find an updated manual but days after days it was obvious that it was really difficult to keep any guide about Ydnar’s great tool updated
I’ve even tried to make a manual by myself, but very soon I understood it was very difficult. You can have the link here, but I seriously doubt that someone can understand it 
So I imagined a simple system working using PHP/SQL. A simple web site of only two pages, where on the first page you can search for a description of a switch/shader keyword/worldspawn key/… by using the embedded search tool. You can also on the second page, if you are correctly logged in, add/delete/modify existing descriptions, add a new q3map2 version, etc…
The main advantage of this is that it requires few time to update it. Simply add the new descriptions once the new q3map2 is out, and you are up-to-date 
I think Ydnar can handle the update of the website alone, because he perfectly knows the behaviour of the new switches.
The first times it will be long to manually enter data into the database, and I will be ready to gave him a hand, and I’m sure some of you are ready too 
Now, the bad point. I have simply no sufficient spare time and knowledge in php/sql to develop and release this ‘smart’ reference guide. So I give you the idea and perhaps if you like it you’ll develop it, you or some friends of yours 
I am sure that if we keep it simple, in one week we can have a workable website.
I’ve wrote a text describing the website, here it is :
Q3MAP2 REFERENCE GUIDE

Select one entry from the results and there is a dialog asking you to confirm delete.
That’s all 
I sincerely hope that someone can achieve the work, as it seems to be clear that we absolutely need an up-to-date reference manual
