Oh Goody! Congratulatory lentils and similar beverages all around! Happy for your success.....

I read this on someone's email signature quote and your ongoing success reminds me of it:

"Freely you shall give. And freely you shall receive." (Not sure of the source)

Thanks for everything you do, Peter.

Hello Peter,

I love and I blogged about it earlier this year at

But recently I always get the error "You are already using the service from the same IP address ( Please log in." (when not logged in) or "You are already using another session." (when logged in).

Is this a known issue? What can I do to fix this? I have only one browser window open (Firefox) and cookies are cleared.

I am asking this here because I couldn't find any user forum, mailing list, issue tracker or any other options for feedback / help, besides the "Comment" box on the browserling site.
