is it possible to delete my threads?

[zebrafink]

Hello,
1.there are elder threads of me which are no longer up to date to me
2.just now I've posted the same thread twice, not on purpose, of course!
Question therefore:
can I delete threads, I have written?
thanks in advance!
Regards,
R?diger

Nope - you'll need to speak to BGAFD Admin and ask/explain.
