If we allowed guests posting we'd probably attract all the spammers, millions of them, lol!
well that is alright Maya,
"For every problem there will be a solution and for every solution there will be a new problem" That is how progress is made in Sciences,
In fact I suggested the same idea to FFI forum long time back and their argument was very similar., But my suggestion to that spam problem from spammers was creating a
"SELF ERASING FOLDER" that to a large extent will filter the spammers and those who are interested in reading/writing/delivering Islamic sermon in to CEMB will join the forum.
And on the way I am sure cembAdms will find new ways to block that spamming.. such as limit the number of posts ,,
