As to the order process.  When you place the order we get an Authorization.  That will be settled pretty quickly and your card will be charged.  Your money will go into a special savings account – call it an escrow account.  Shipping should be sometime Late October/ Early November.

For those of you international, place your order w/out the credit card option.  I’ll get an accurate shipping quote for you via email and you’ll be able to pay by Western Union, Money Orders or Wire.

Please report any problems you are having to sales@ueusa.net or tell me here and I’ll fix them asap.

Yes folks, after what seems like years (and is) we are finally live with the new site.

Yes, we know it’s not perfect. But if you’ll report bugs either here or via email (sales@ueusa.net) we’ll fix them as quickly as we can.

Https (SSL) should be site wide now for a safer environment.

Automatic forum registration should be back running w/ reCAPTCHA to keep the bots out.

Some things we lost
The Activity Center in the forum. That little custom script will need to be re-written for the latest version. I don’t know how many of you used it, but I really liked it.
Order history. This will come back soon, but the new store is a mishmash of about 6 different tables doing the job of what 2 used to do, so it may take a bit before we can import them. I know, I want them too.
All the bot users in the forum. Purged. Things should run faster.
Flat rate shipping. I was losing my hide on freight so now we are getting live quotes from UPS. What it costs is what you pay.

Things still on my hotlist
A physical inventory.
More pictures for the store items.
More engineering 
New skin for the forum and gallery
A little better flow from the store menu structure. It’s close, but things don’t always flow the way they should. It’ll be improved soon.

Let me know if you have problems and we’ll fix them as quick as possible.
