@TRiG sure. The Purim book isn't all Purim Torah; there's serious stuff in there too, and likely the majority. The PT is for fun but it's not the only content.
@YEZ There's an arrow at the top left of it (as there is at the top left of this post). Hovering over this post will lightly highlight yours, to which it's a reply; clicking the arrow will heavily highlight yours (and scroll to it if necessary). Isaac was replying to TRiG's question whether readers will take seriously a suggestion, Purim-time, to get hold of a hagada, by linking to information on sh'loshim yom kodem hechag.
To link a post of yours as a reply to a previous one (highly recommended where appropriate, as it helps people follow a conversation), do as follows: Put your mouse over the post to which you wish to reply, and an arrow will appear at its bottom right. Click that arrow, and the post-editing box will get a colon, a number, and a space in it. Type the rest of your post after that space, and it will be marked as a reply to the post you wish to reply to.
