Lol; think I'll skip that. But I'll give helpful comments about why:
1. Proboards (Yuk)
2. Proboards site, not self-hosted; no sure if you can self-host a proboard but hey.
3. Ads, got a Popup Blocked message when I went on and that huge great Ad at the top.
4. even the Domain Marker is a .tk - which also puts me off.
5. Proboards; just generally not nice, not nice style either although, again, Proboards don't have such a thing.
Just some suggestions:
1. Get hosting; and host a PhpBB Board. Some people like .tk - so thats just me moaning more than anything else.
