It's probably better to use:
[netreceive ...] | [list prepend text] | [list trim] | [textextruded ...]
as you don't need to concat the list to a single symbol, [textextruded] can handle a list of symbols as well, also you don't need any more externals then.

hi PDers, thanks for previous help - i have now got basic messages going over
tcp, but am having trouble passing text messages to PD. the
problem is spaces (and the first word getting dropped).
What problem are spaces? Regarding the first word being dropped: YOu may want to read up a bit on how messages are handled in Pd, e.g. here: http://puredata.info/dev/PdMessages
Basically it's like this: Messages in Pd have two parts: A selector, which is the "first word" from above, and the actual message data. The selector is "float" for number messages, "symbol" for symbol messages, "list" for list-messages and other words for "other" or meta-message. As a special rule, a message without data is converted to a "bang" message, and messages, whose data part start with a number, can omit the "float" or "list" selector.
[netceceive] will spit out whatever message type you send to it. So if you send "text pi pa po", it will output a "text" meta message, if you send "list a b c", it's a list-message, if you send "hello world", it's a meta message with selector "hello" i.e. a hello-message.
Now the tricky part that was wrong in your patch: dollar variables in message boxes like [hello $1( take the replacement values from the *data part* of incoming messages. The dollar variables ignore any selectors. See attached patch for an example.
Note that some selectors actually make a message box do special things, like the "set" or "addsemi" meta-messages.
