<span size=\"large\">There are still several issues and bugs to be worked on,\n\
as well as general workflow improvements, before this can be considered\n\
release software. So, a few guidelines:\n\
\n\
1) Please do <b>NOT</b> use this software with the expectation that it is stable or reliable\n\
though it may be so, depending on your workflow.\n\
2) Please wait for a helpful writeup of new features.\n\
3) <b>Please do NOT use the forums at ardour.org to report issues</b>.\n\
4) <b>Please do NOT file bugs for this alpha-development versions at this point in time</b>.\n\
There is no bug triaging before the initial development concludes and\n\
reporting issue for incomplete, ongoing work-in-progress is mostly useless.\n\
5) Please <b>DO</b> join us on IRC for real time discussions about %1 %2. You\n\
can get there directly from within the program via the Help->Chat menu option.\n\
6) Please <b>DO</b> submit patches for issues after discussing them on IRC.\n\
\n\
Full information on all the above can be found on the support page at\n\
\n\
http://ardour.org/support</span>\n\
