during the last three weeks this Web site has experienced some problems in sending e-mails. The problems have been solved.
About the Forum issues (PHP5 compatibility) you probably noticed (I didn't post about this) that I solved them some time ago, without upgrading Phorum; the only problem is an annoying error message that you can see viewing a post detail without being logged-in (e.g. http://www.dadabik.org/forum/read.php?f=1&i=10323&t=10323) but the forum is totally usable.
I want to thank Rainer Scheidegger for this, who pointed me out a very simple solution.
