hey Shahjahan Jewel I have filled the form to access the beta-version of FluentCommunity in September, but never received the download-link. I tried again today, but didn't receive the email either
Sascha the download link is on the top of this Space feed so you can get it at anytime. Also you can read the unofficial starter guide to become more familiar when starting for the first time.
Happy testing!
Ps. Don't forget this is still Beta so please share your feedback here later on so the fTeam can be happy too.
