Hi guys, i just have an idea...you can put a search engine in the forum, so it will be very easy and quicky to find the thread that you are loking for.
An engine that search only in the titles of the threads.
I say this because some section have a lot of pages and if you want to find something you have to open all the pages.
I know there are free search engine that you can add on your website on the net...
Mine is just a suggestion, the forum is very well structured already!!
