Caveats

Messages sent on channel zero^[1] and DEBUG_CHANNEL are throttled to a rate of <200/10sec, per region, per owner/user.
- Once the rate is exceeded, all following messages on channel zero or DEBUG_CHANNEL will be dropped until the send rate is again below 200/10sec for the previous 10 sec. Dropped messages, despite being dropped still count against the limit.
Text can only be a maximum of 1023 bytes.
Shouts can only be heard within 100 meters of the speaking prim (rather than the root). This is contrary to how listens work, where a message can only be heard by any prim in the object if and only if the root prim is capable of hearing it.
A prim can not hear itself, this to prevent problems with recursion. It can however hear other prims within the same object.

For communicating with the user or owner it is much better to use llDialog, llOwnerSay or llInstantMessage as they won't spam other users.

^ Channel zero is also known as: PUBLIC_CHANNEL, open chat, local chat and public chat
