How to use forms of others?

Hi all,

I developed a bounch of Form applications and need to put them into use. My question is how to let the end users access only one set of tables. One way is to change each block definition so that each end user use X.TABLE (blocks were designed to belong the current user) And then grant the end users select and DML. But what is a pain! Are there any easy ways to do this?  

Thanks for you help in advance!   

Please email me if/when possible since I seldom to read news.
