i once deleted my posts from the sticky thread on differential forms, because i do not agree with PF's strong censorship policies, and therefore do not want my words posted there in perpetuum. if you are not willing to allow me to remove the words which you asked me to copy and paste here from sciforums, then would you at least make the thread not sticky? I do not feel comfortable with this forum using my hard work to represent itself against my will. it seems to me that in the interests of honesty and full disclosure, you should make clear in you site guidelines that PF reserves the right to keep your copyrighted works forever once you have deleted them. it also seems to be that whoever (re-)posted my copyrighted words to that thread was in violation of PF's policy of not infringing on copyrights (although IANAL). it is an underhanded trick. I hold the copyright on my words. I ask you to at least remove the thread's sticky status if you are unwilling to allow me to take my ball and go home.
