Re: [wtp-dev] Re: Direction on using installable runtime extensions

[Angel Vera <arvera@xxxxxxxxxx>]

Hi Rochelle,

Tim is back next week, but if you have
more question feel free to send me an email, don't wait for him. I can
probably answer your question.

This mailing list is mainly for communication
between all the WTP developers, we also have some newsgroups setup that
are more suitable for any kind of questions. I think is just bad timing
as we were all heads into closing M6.

Let me ping the wtp team responsible
to reply to your note and bring your note up to their attention.


Best Regards,

Thanks for your response, Angel.  When will Tim
return?  I filed 
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=226061> and hope to
see 
it fixed soon!

Also, other questions I've sent out have not been answered until I send
a second request as well.  Is there a better list for these types
of 
questions or is it just an unlucky coincidence =)?

Thanks,
Rochelle
