"Do you know if it is POP3 compliant? It looks like you can't tell w/o signing up!"
I suppose somebody is going to respond to your question by saying something like...
"Gee in the time it took you to go to the site, check it out, and come back to this forum and post your question you could have just signed up and found out for yourself. Are you the kind of person who asks the waiter to cut up your food into bite sized chunks?"
But I won't say anything like that, for all I know you're not yet a fully formed, mature, self-sufficient adult.
The answer to your question is: No.
BTW, If anyone does post a snide remark like that, go tell mommy and daddy, they'll make the hurt go away🙂
