Can't Edit My Profile
Sorry to call this much attention but I've been asked to edit my age from my profile and the save button doesn't save the changes I've made. If a mod has the power, and if they feel its really a pressing necessity, please edit my profile for me... if the mod cannot, my apologies, I'll keep trying. :)
Hi, you should be able to edit your biography displayed on your profile page in your profile settings and save the changes you've made.
