The requirement for first/last names on TTB posts adds to the integrity and credibility of the information here, making TTB more of a service to the hobby. And as has been said, first/last name included in a signature satisfies that requirement. But names in sigs aren't required for those who prefer not to do that for posts outside TTB.
For those who have elected not to have both your first and last name in your signature, I'm sure you are as tired of forgetting to include it in TTB posts and being reminded as the mods are of reminding you. So here's a workaround ...
If you will make a post in this thread with your first and last name, that requirement will be satisfied for all your TTB posts. Anyone who wants or needs to know who made a post can check this thread.
I hope this is a solution that will make life in TTB easier for all concerned.
