My journal is semi-locked because I tend to lock the entries that discuss my personal life.
I will add anyone who asks me to. :) If you do not ask, then you will not get added back.
Commenting is partially a big deal. I rarely do "friend cuts" but I do go through my profile occasionally and clean up. You do not have to comment all the time. BUT if you have friended me and never commented on my posts, then I am going to remove you. If you have commented at least once and tried to get to know me then you have nothing to worry about. :)
If you are looking for my graphics, they are posted at g_b_icons.
