WOW! Just wow!

Thanks for your hard work, Victor, I know it is very much appreciated by all.

I second Paul's comment!! Love the break down of objects to different sized scopes, etc.

In order to keep the bots at bay and to keep CSOG downloads in control, I have added a registration and login page (https://clearskies.eu/csog/downloads/registration/) to the website. All that is required to download CSOG content is a username and a password.

I am contemplating to publish CSOG 2.4 as an interim update. Despite I am almost ready to push only two new editions, for northern (KTG) and southern (KTS) Karachentseva triples, the updates to and enhancements of existing content will be quite substantial.

I created an account then got a message saying I was temporarily blocked from the site. Today I tried again but still no access. I never received an email with the activation link when I created my account. These look like they are very nice but I can't get to them.

I resent your verification e-mail. Please feel free to contact me at victor@clearskies.eu.

Thanks. The email was in my spam folder but I got logged in. Clear Skies!
