Users would read that message when the webapp is already installed, so the
message can be confusing.

You have no computers registered. You can add a computer here by clicking
$boldBegin$$buttonName$$boldEnd$ on the computer you need to access.

[Jamie, 2012/06/28 22:07:12]

I think that's an improvement, but it doesn't tell them where to find that
button (on Chrome OS there is no such button on the local app, so it's
non-obvious). How about:

You have no computers registered. You can add a computer here by installing
Chromoting on it and clicking $boldBegin$$buttonName$$boldEnd$.

SGTM, although you need to brandify Chromoting. :)

might be better to use $1 for the message itself while $2 and $3 for <b>. Why
can't <b> be part of the resource itself?

[Jamie, 2012/06/28 22:07:12]

If the HTML tags are part of the resource then it's possible for translators to
change them. I've used this approach elsewhere to preserve markup in l10n. I
think I'd prefer to keep the placeholders in the correct order.
