yeah, i did several times & i only have 2 emails addy's to use, so it was quick work.
same thing happened on the v-twin forum so i simply re-registered at both places.
i am guessing if one registers, lurkes & never posts, eventually a registation may get the boot after in-activity.
perhaps like the old, REALLY old, yahoo email accounts. i had several for junk mail & i guess i let them fill up & never went in so after a certain amount of time they seem to "expire". something like that.
