Today I found the following quote from this site, I recommend any slack user will never go to this site until its construction is ready !!!
** Because of the many false package requests (over 300 were incorrect), I had to clean the requests db table.PLEASE, report ONLY the packages that really have newer versions! If a package doesn't runs for you, check the dependent libraries, and download them. If it still doesn't work, use the forum to tell me what you get and why I should rebuild it. Recently I don't have much time for this site :( **
