About the hosting
The members will notice that the poll has disappeared. I think enough people have cast their vote for me to reach a decision. You will notice in due course what it is, as I have to check other arrangements that may have to be made if we switch host.
About the two themes
Some of you members were disappointed that I had removed the Dipteran Blue theme. Through Edit Profile it was possible to get the theme back but then you got stuck with the green site banner. That has now been solved. Choose the Dipteran Blue theme and you get the blue banner as well!
Green theme is back
Of course you have noticed I have switched back to the earlier used green theme. The Dipteran Blue appeared to be loved or hated. The main complaint was that the blue theme was tiring on the eyes. For members who prefer the Dipteran Blue, they can change it in their profile but you will be stuck with the green-coloured banner.

Another added feature for the members, you may have noticed, is the possibility to create personal favourites for the site and store them. They will be available at every visit when you logon. The panel is at the bottom left. Go to the particular page, fill in the name you want to give to the link and click the button. Easy as that.
10,000 visits!
The 10,000th unique visit coincides with an upgrade of PHP-Fusion from version 4.01 to 5. The average visitor will hardly hardly notice the upgrade, unless there are some unsolved issues. If you find any errors, please send them to me and I will see whether it is because I installed it incompletely or that the system shows some quircky behaviour. You can use the Contact Me link (everyone) or the Private Message system (Members only).

International Code for Zoological Nomenclature on-line
Finally, it is available on the web. For those of use who like to know why species names have to change (at least some of them) and why some of the proposed changes are invalid: check out the International Code for Zoological Nomenclature. You can find the link in Web Links -> Resources section.

A keep checking the other sections as well. New web links are added regularly!
