I see. Personally I have never found the need to accept a friend request that I rejected/declined earlier, which is why it was not in the original script to begin with. From the technical point of view, its not a difficult task to implement. Just need to delete the data from the friend request table(instead of updating its status to be declined/cancelled), which will allow friend requests to be sent again. If its really desirable, I can make this feature available in Mys v1.3.6 the next release, though I think some of you cannot upgrade to the new version.
