Thus the name "metaexchange" is good, but I would also consider a shorter more brandable name such as meta.exchange, metaX.trade, meta.trade, etc.. I see the following choices are available for domain registration:
emetatrade.com ($6 right now at namecheap.com)
emeta.exchange
emeta.trade
Grab it now!
I strongly suggest you change to a slightly more brandable domain and name.
P.S. I had a fundamental error in my recent discussion with you about "inertia" but I left it as for the moment to keep potential competitors off course (and also to conserve my time for programming). Will come back to that soon to correct. Best we will dig into that once I am ready to go 100% open source (soon again).
Believe it or not, we have actually been operational for 1 year already, so there would be a high marketing cost to losing all our external link rankings and referral traffic by changing the domain name

whois.com has .trade and .bid domains on sale for $2.88. I think you can afford that, lol.

You can purchase superior domains and decide to make them optional, so you don't lose your existing traffic. Just use them in your new promotions and have the time autoconfigure its web pages for each name. Overtime you can monitor to see which name sticks and then phase out promoting the other ones. Hey you should know this already, else it means you really don't have sufficient experience in internet marketing.
If you want to scale to big time, then .info seems like a strange appendage to me, but better to let your market decide because my personal opinion may not be representative of your target demographics.
These are available:
emeta.trade
ometa.trade
xmeta.tradeSeems more memorable and concise than, although you'd want to grab all the meaningful one letter permutations above redirect them to your preferred domain and not having
meta.trade sort of ruins some of the potential advantage:
metaexchange.infoA slight improvement over
.info in my opinion is:
metaexchange.bidBut I'd prefer
meta.exchange or
metaexchange.com, which are already taken, thus
metaexchange.info is not widely brandable.
Perhaps:
metaxchange.net for $3.88
metaxchange.bid for $2.88
metatrade.bid for $2.88
metatrade.co for $2.78 (at namecheap.com)
emeta.biz emeta.trade meta-e.biz for $2.78 (at namecheap.com)
meta-e.co for $2.78 (at namecheap.com)
meta-e.net for $3.88
meta-e.trade for $2.88
bitmeta.net
bitmeta.tradetransmeta.biz
transmeta.co
transmeta.org
transmeta.tradetransmogrify.bid (joke)
metaspan.biz
metaspan.co
metaspan.tradetranspand.bidtranspand.com for $5.88 (at namecheap.com)
transpand.net
transpand.tradeBut there is no clear winner, so maybe stay with your existing name. Of all of those, transmeta is the widest brandable, but within a narrower demographic sphere (which may be the case for your market) maybe metaexchange is more clear even if there are other companies with the same name but don't overlap your market.
