If i replace

type="submit"

to

type=""

in submit button, i can posting message without timeout between messages (option in settings - antiflood).

For more information:
Default system: user sends a message and waits 3 (for example) minutes before sending next message.
Current system: If i remove "submit" from attribute "type" in submit button, i can sending next message without waiting of ending timeout. This bug causes problems with spam.

Please, fix this bug. Thanks.
