Its the quality more than anything, most of them look amateurish - which of course they are - not intending to offend anyone.
Ill have a go if I get some spare time, but really we need a resident graphic designer to come up trumps with something a little more slick than Arial 12, italics, drop shadow and texture effect.
But there is a need to know the final forum design too. No point doing a red logo if your gonna change the froum to blue etc
Well even we dont know that yet, but the header can remain a seperate entity to the rest of the look, thats how we got away with a reed skin, a silver skin, etc before. Safest bet is to probably assume well stick with a blue or silver theme? Were not likely to go for anything gaudy after all.
Just to reassure, Im not taking the mick out of anyones efforts, its just that none quite look polished enough compared to our original logo and some have aspects totally unrelated like clovers or Fisher Price colours.
