It is pretty straightforward. How exactly you set it up will probably depend
on your security requirements... The general process would be to make a DTML
method for updating an item that posts to another DTML method. The "update"
method would do something like:

<form method="post" action="SaveChanges">
<input type="text" name="name" value="&dtml-name;">
<textarea name="problem">&dtml-problem;</textarea>
<input type="submit" value="Save Changes">
</form>

then the "SaveChanges" method could do something like:

<dtml-call "propertysheets.basic.manage_changeProperties(REQUEST)">
(replacing "basic" with the name of your propertysheet)
<dtml-call reindex_object>
(if it is a CatalogAware object)

KM|net News has a working example of this, if you drill down to the
KMArticle ZClass and look at the "edit" and "postit" methods.
