'Webark', it would sound like 'We bark'. That would make people think of the noise that dogs make. It might work, though, if you put a capital 'A' in the middle of the word, as in WebArk. This isn't possible in 'normal' English, but it's a common convention for company names.

It's strange. I can't help reading it as "We bark." Su.Ki's suggestion only works in print, because URLs are customarily presented in lower case. The technical situation regarding case-sensitivity in URLs is a can of worms, but let's just say that it would be a bad idea to use www.WebArk.com as a URL. What does the "Ark" part actually stand for? What does the company do? The problem of unintended word boundaries comes up in real life. There is a real company that is a directory of literary and performers' agents. If you want to find out "who represents" an artist, you go to their website... which is www.whorepresents.com . Unfortunately, you can also divide those letters into the two words "whore presents" which could mean "gifts for prostitutes." They are very careful to display their address as "WhoRepresents.com" but if I type that into my web browser it quickly redisplays it as "whorepresents.com." The company's been on the web for many years and obviously that company feels that it is better for them just to leave the name as it is than to change it.

No, about web :)

Is it a company about pets?
