Save the accounts ?

Hello everybody,

Well, I already tried on mail-news and on general, but I have got 
difficulties to believe nobody knows how to do.

I shall have to reinstall Mozilla as it refuses to post to two 
newsgroups, but beforewards I should like to save my accounts, to avoid 
reparametering them afterwards.

I reinstalled Mozilla on my admin Windows XP account, the postings run 
quite OK, but it seems it has to be done on my "restricted" Windows XP 
account. Shall I be able to avoid re-doing everything from splash after 
reinstalling ?

Google found no topic with "account" or "configuration" in the subject 
in this newsgroup. Any better search key ?
