mrexcel.com home page.
On the left there are a number of links (About MrExcel, Consulting Services etc.) and this is where the "MrExcel Store" link can be found.
It is still requiring a username and password.
Thank you for the information.
It was somewhat suspicious because it was asking for a username and password - that would be sent unencrypted!
Perhaps next time they should either disable the link or, better still, display a message when it is clicked to state why it is unavailable and for how long?
Hopefully the MrExcel Store did not lose too much business.
