I have just learned something the HARD way!
All of my listings contained several links - to my About Me page, to Join eBid, and to my ONE store.
I later opened another store, and in doing so, changed the registered name (slightly) of the original store, so as to distinguish them from each other.
Hey Presto! - my 'Link to my Store' in ALL my listings, did not work - I had forgotten to change the original link to the newly named store link.
Going through every one of my auctions then running (and there were only about 90 of them) and changing the links took a long time...
... So (especially to those new to listing) a word from the wise (after the event) - ensure that you are happy about ALL aspects of your listings defaults before you commit them, as once your listings are up and running, it will take a lot of work to amend any links within them that are no longer valid.
I should have thought it through BEFORE I opened a second store, but being dumb and stupidI rushed to create the new store, and rename the old one, without considering the consequences. I admit it! Also, this scenario applies to links within your About Me page AND in your Signature Link on the Forums ... so please be warned
. Buyers are very likely to be put off if they click on one of your links that goes ... nowhere!
