Re: [PDO] PHP ext/PDO future

Hi Lukas,

        Yes, Kellen is now not working on the IBM PDO extensions. Here is 
a brief introduction to the team that is currently working the IBM PDO 
extensions.

Mario Ds Briggs 
Ambrish Bhargava 
Tarun Pasrija 

        We would like to see the communications happening through this, 
[email protected], mail address so that in the absence of the above 
mentioned team members others can take over the task of handling the 
issue/information that drop in. 

        Ambrish has already requested for an account on PECL to maintain 
IBM PDO extensions.

Thanks,

Praveen 

IBM OpenSource Application Development Team

Re: [PDO] PHP ext/PDO future






Hi,

I hope everybody was just busy with other stuff over the weekend (like 
it should be) and now that the east coast people should be waking up, 
we will hopefully start to have some sort of a discussion.

At any rate it seems that Kellen is no longer working on the IBM PDO 
extensions, so I replaced his email with [email protected], which is 
the general team at IBM that is tasked with maintaing their PDO 
extensions now it seems (hopefully we will soon get a personal 
introduction by one of them).

Due to the changed email address, I have included the entire original 
email again and please reply to this second email and not to the 
first. Also please keep the entire CC list intact for now until we can 
be confident that all relevant and interested people have subscribed 
to this list.

regards,
Lukas
