Reply: We are borrowing translation engines from Google, Microsoft and Baidu as their API services. Their translation programs are too big and complicated to be installed at personal computers.
Therefore, there is no way you can use them off-line. Instead, if you are connected on-line, you can use these high quality translators from all over the world.

Reply: Thank you Judy. We are also growing with our visitors' support. Happy New Year!

Reply: Thanks.

Reply: Now we are using our own Spell checking server instead of Google spelling server that seems to be discontinued recently.
Again all our spell checkers are working normally. You can get them at All Spell Checkers and for Russian at Russian Spell Checker.
Thank you very much for your advising us on this issue.
