Yes, it's a very good idea to get your plant's inventory updated, it's beneficial to the poster as well as to other members in this forum, as was already stated.
As an alternate, I just listed my plant inventory/wanted list in docs.google.com's spreadsheet, then pasted it's url into the URL box of the Modify Profile page. To open it, one would need to do a copy and paste. (This box was probably originally intended to be filled with your home page's url-if you have one, so this method may not be acceptable to the Moderators.)
To make it simpler, and probably more convenience also since one needs only do one click right there at the forum's discussion page without going through the steps to get to the Modify Profile page, I pasted my spreadsheet's url right below my "Signature"; just like some people here do it already, to show their home page or their custom signatures...
Cheers!
edit: make the link shareable
