we were experiencing a slow page refresh rate after posting messages in the forum, and we finally found out the problem.
Unfortunately, when we found the problem, we also realized that the mail box of recent subscribers were spammed with test emails.
Please accept our apologies.
The cause for this behavior was a wrong setting for new subscribers. Basically, new subscribers were set to “All emails” by default (against our will).
We have now manually moved the option to daily digest. You can switch to no emails/weekly/new topics if you would like.
