I was just thinking : strange, I didn't received a message since I left for Mexico! And then, I tried to send myself an email (to the admin account, see at the bottom of the page for the address). Didn't receive it! Turns out that my mailbox had a very small default quota (10 megs), was setup to keep every message since the beginning AND had a special 'spam' folder that I didn't have access to using my POP email reader on my desktop.
Cleaned the mess, and now I can receive emails again. I apologize in advance if you tried to contact me; just do so again! admin @ biologynews.net ... comments, suggestions, design ideas, problems, etc... I always love to hear from you ;)
