do old threats get deleted?

[glurps]

like most of use i was able to solve many problems using this forum. sometimes it happened that i had to do the same thing again but had forgotten how to do it, so i looked the threat up in "you postes" but sometime ago old threads disappeared from that list.

now i am wondering if they were completly removed or only from my personal list?

if they were not deleted: how can i find them again? just searching with my username didnt help.

thx
