There are some problems, particularly from old contests, whose editorial is hard to understand(as it is not explanatory enough) and leaves me clueless regarding step(s) in the editorial.

Posting a blog for every problem whose editorial I couldn't understand doesn't seem like a good way to ask for help.

Where should I ask for help in such cases? Is there any discord server/telegram channel/any other thing where other people are active and I can ask for help for problems rated 1700-1900 ?
