Three questions ...
1. Based on 0.95 MODx maturity, are there real-world limits on the number of members in a user group for sending emails efficiently, besides those imposed by ISPs and PHPMail, sendmail, etc? For instance, can I send an email usefully to 1,000 people? Yes, I know 1.0 will not only cure cancer and end global warming/cooling/whatever but automagically write as well as send email even before someone has decided one is needed

.... Meanwhile ....
2. Will the message text area parse html correctly or does it handle plaintext only? This is a lazy question, I know, but I figure I’m sandwiching it between two others I cannot answer adequately.
3. Can users be imported into MODx in the Manager? Alternatively, how difficult would it be to import them directly into the database?
Partly, this has arisen from my frustration with trying to get the Koops list thingy to work. Mainly, the relative ease of doing the above, if feasible, would meet some other needs. Someday, I will join the illuminated ones who understand MODx <----> Koops over on its psychiatric support thread, but I hope it won’t be soon. The migraines are too painful ...
