i just found this site and i think its great i love all the features that it has but does someone know how or where i can create themes for my sony ericsson w800i please help!

Check the FAQs to find the programs you need (under "what software to make themes). It is the sony ericsson theme creator that you want.

Check the stickies in this forum:

If you need another reference to look at here's a guide for the T610 which i followed: http://members.lycos.co.uk/mosedrengen/tutorial/ But you'll have to adapt it to suit the W800.
