Problem with new SCN

hello Guys,

i am afraid with new SCN, i am regular user of SDN but now i am facing many problems with new SCN like below:

1. how can i see my old postet questions ?

2. how can i see the regular update on my questions ?

3. how can i get the option for searching in forums ? suppose i want to search somthing related to issues then i don't see any option...

4. every time it gets logged out even i did remember password.

is it possible to rollback to old SDN ?

Regards
