JabRef's discourse includes creating a poll when creating a new "Features" topic, however, new users are not allowed to create polls

Below is a little bit obscured default template for the creation of a new topic on https://discourse.jabref.org/ . It is, however, impossible to create a topic according to this template, since poll creation is restricted for new users (and maybe for someone else too).

Here comes the feature description....

Please vote if you support this proposal:
* I would like to have this feature, too!
* I don't care.

I tried it and successfully created a poll

Very good. Please continue helping to debug this until the particular configuration when creating pools fails is found.
