Hi,
I met someone who had a nice solution for it:
paste into aliases:
/gnr2 /nickserv ghost yournick yourpassword | /Nick yournick | /nickserv identify yourpassword
The perform should look like this then:
/gnr2
/join #yourchannel(s)
/Nickserv identify yourpassword
/timer 1 10 /nick yournick
/timer 1 5 /nickserv release yournick yourpassword
Thanks to all ppl who were so supportive and special thanks to ORCUS, user on german-elite.net, who came up with the last solution, which works great.
