This sounds awesome, I'm going to download it right away.
Two things, though.
Generally when linking an add on that has already been uploaded to te4.org someone will just paste the URL for the add on in here, as so:
http://te4.org/games/addons/tome/neka_qol01.
That's what it's there for, after all! (Plus, it avoids uploading your file to the te4 server twice
)
It will also let players see the rating, how many downloads it has had, and any comments you may have received (such as that one from
DarkGod 
).
Also, after having uploaded your add on, you can log into your account on te4.org (same login you use when you launch ToME) and then you will be given the option to 'edit' your add on's page (the page linked above). On the edit screen you can add a link to the forum discussion thread (i.e. this one) that will appear just below the "See Addon Usage in Character Vault" link. (Because, while you can have comments on your add on page, this is generally a better venue for active discussions.)
The other thing is off topic, again, but this just reminded me of something you may need to watch out for: file size. I believe the limit for uploads to te4.org is around 5mb (based on the OldRPG Tile Set file sizes). I think you should be fine for Odyssey of the Summoner (assuming it's still around 4mb), but if it grows any more you may want to consider splitting it into parts.
