I'm totally a lurker on this site - I only very occassionally log in and actually post something. But I come on here and have a look most days to see if I can pick up some new tricks
As you mention the community is great but is experiencing a slow death. New people just aren't visiting the forums anymore - but, I imagine the best way to increase visitors to the forums would be to increase visitors to the main site itself.
I agree that the main site content is already good. However, some redesign would be great. For instance, embedding videos, instead of having to download them or stream them in WMP. Nowadays, people want instant access - you read about a technique, and watch an embedded video at the same time - This is basically what you guys do in the forums anyway, you describe something, then you upload a video to youtube. This is where EF falls at the wayside compared to somewhere like http://www.insidesoccer.com
Is Expert the same guy who did all the original videos and the main website? Does anyone know where he went?
If someone had the time (and permissions) to revamp the main site, add some videos, tighten up the content, re-start up the "ask the expert" section etc, then I'm sure people would come. I mean, there are enough kids out there wanting to learn football that this could become the number 1 site out there...
