From past experience submitting a component to the JED can be tricky specifically the files. I need to add 465 in front of my components name to ensure it is unique and doesn't get rejected from the JED. for example com_465xxx. When I put any numbers it doesn't save.

In fact, numbers are not allowed in this version.

We put this on the list, good idea, thanks.

Done.

Works only if numbers are not in first position.
