There is nothing at all wrong with wearing the OLDA tag...I do it. If and when you join a clan, if the OLDA plus clan name is over 8 letters, than an admin will make you change it, but no, wear it as much as you like

To get OLDA clan up and running again, well, we would need a lot of over 19 people who are dedicated, and active, and clanless. That was why OLDA became an org in the first place, most of our members are already in active/great clans and dont want to leave. If you want to do it though, feel free, I may even ask light if I can double clan in that instance :P
